Vanadium Oxide-Tungsten Oxide is a mixture of vanadium dioxide and tungsten trioxide, which is used in physical vapour deposition to deposit thin films with both thermochromic and electrochromic properties on the substrate. It can be used in the field of smart windows to regulate the light and temperature more accurately, and in the field of displays to achieve the flexible switching of multiple optical states.<\/p>\n
VIMATERIAL supplies Vanadium Oxide-Tungsten Oxide sputtering targets with 99.9% purity. Our Vanadium Oxide-Tungsten Oxide sputtering targets have the advantages of adjustable phase change temperatures around room temperature, combined thermochromic and electrochromic properties, improved film densities and adhesion, and the possibility of expanding to multiple applications and good compatibility with existing processes. We have been working on inorganic chemical industry for many years. We have been working on inorganic chemicals for many years, and we also provide sputtering target binding service. We have an experienced and professional team to accept customisation and experiments, please contact us<\/a><\/span> if you need.<\/p>\n Molecular formula: VO2\/WO3<\/p>\n Appearance: Dark blue to grey in colour<\/p>\n Electrical properties: Combining the thermochromic properties of VO\u2082 and the electrochromic properties of WO\u2083, the electrical properties are more varied at different temperatures and electric field conditions, allowing for more flexible regulation of conductivity.<\/p>\n Optical properties: The optical properties of the film such as transmittance and absorbance in the visible and infrared light regions can be optimised by adjusting the doping ratio and preparation process, so as to meet the requirements for optical properties in different application scenarios.<\/p>\n Smart windows: Vanadium Oxide-Tungsten Oxide doped sputtering targets can be used to prepare smart window coatings, which can precisely regulate the light transmission rate of windows according to the changes in ambient temperature and illumination by taking advantage of their thermochromic and electrochromic properties, achieving a dynamic balance between indoor lighting and heat insulation, and reducing the energy consumption of buildings.<\/p>\n In the field of display devices: In liquid crystal displays, e-paper and other display devices, the thin films deposited by the doped target can respond to changes in electrical signals or temperature, quickly switching the optical state, enriching the display colours and contrast, and enhancing the visual effect and interactive experience.<\/p>\n Infrared Detection: Used in infrared detector surface coating, with optimised thermochromic performance, it can accurately change the infrared absorption and reflection characteristics with subtle changes in the temperature of the target object, enhance the detector’s ability to capture weak infrared signals, and improve detection accuracy.<\/p>\n Optical storage field: Vanadium Oxide-Tungsten Oxide doped sputtering target is used to make optical storage media, combining the special photoelectric properties of the two, to achieve higher density data storage and fast read\/write through temperature and electric field regulation during laser writing and reading, to meet the needs of the big data era.<\/p>\nPhysical Properties<\/span><\/h2>\n
